Hydrochloric Acid → HCID 53654790, compound

Participants

Reaction Steps

101.5 gm (0.905 mol) of potassium tert.butylate, suspended in 500 ml of dimethylformamide, were admixed, while stirring and cooling under exclusion of air, with 96.0 gm (0.905 mol) of thioglycolic acid methyl ester. To the solution of the potassium salt, the mixture was admixed with 205.9 gm (0.822 mol) of 1-chloro-1-(2'-fluoro-4-biphenylyl)-propane [prepared by reduction of 2'-fluoro-4-biphenylyl-ethylketone with sodium borohydride and subsequent reaction of the obtained 1-hydroxy-1-(2'-fluoro-4-biphenylyl)-propane with hydrochloric acid in benzene], and the mixture was stirred for 4 hours at room temperature. Subsequently, 2 liters of water were added, and the reaction product was isolated by extraction with ethyl acetate, and washing, drying and evaporating of the extract. Yield: 254 gm (97% of theory); oil, Rf -value: 0.5 (cyclohexane-ethyl acetate = 9:1 on silicagelpolygram-plates).
